Human Gene MCCC1 (uc003flf.3) Description and Page Index
Description: Homo sapiens methylcrotonoyl-CoA carboxylase 1 (alpha) (MCCC1), nuclear gene encoding mitochondrial protein, mRNA. RefSeq Summary (NM_020166): This gene encodes the large subunit of 3-methylcrotonyl-CoA carboxylase. This enzyme functions as a heterodimer and catalyzes the carboxylation of 3-methylcrotonyl-CoA to form 3-methylglutaconyl-CoA. Mutations in this gene are associated with 3-Methylcrotonylglycinuria, an autosomal recessive disorder of leucine catabolism. [provided by RefSeq, Jul 2008]. Transcript (Including UTRs) Position: hg19 chr3:182,733,006-182,817,365 Size: 84,360 Total Exon Count: 17 Strand: - Coding Region Position: hg19 chr3:182,733,226-182,812,390 Size: 79,165 Coding Exon Count: 16
ID:MCCA_HUMAN DESCRIPTION: RecName: Full=Methylcrotonoyl-CoA carboxylase subunit alpha, mitochondrial; Short=MCCase subunit alpha; EC=18.104.22.168; AltName: Full=3-methylcrotonyl-CoA carboxylase 1; AltName: Full=3-methylcrotonyl-CoA carboxylase biotin-containing subunit; AltName: Full=3-methylcrotonyl-CoA:carbon dioxide ligase subunit alpha; Flags: Precursor; CATALYTIC ACTIVITY: ATP + 3-methylcrotonoyl-CoA + HCO(3)(-) = ADP + phosphate + 3-methylglutaconyl-CoA. COFACTOR: Biotin. PATHWAY: Amino-acid degradation; L-leucine degradation; (S)-3- hydroxy-3-methylglutaryl-CoA from 3-isovaleryl-CoA: step 2/3. SUBUNIT: Probably a dodecamer composed of six biotin-containing alpha subunits and six beta subunits. SUBCELLULAR LOCATION: Mitochondrion matrix. DISEASE: Defects in MCCC1 are the cause of methylcrotonoyl-CoA carboxylase 1 deficiency (MCC1D) [MIM:210200]. An autosomal recessive disorder of leucine catabolism. The phenotype is variable, ranging from neonatal onset with severe neurological involvement to asymptomatic adults. There is a characteristic organic aciduria with massive excretion of 3-hydroxyisovaleric acid and 3-methylcrotonylglycine, usually in combination with a severe secondary carnitine deficiency. SIMILARITY: Contains 1 ATP-grasp domain. SIMILARITY: Contains 1 biotin carboxylation domain. SIMILARITY: Contains 1 biotinyl-binding domain.

The RNAfold program from the Vienna RNA Package is used to perform the secondary structure predictions and folding calculations. The estimated folding energy is in kcal/mol. The more negative the energy, the more secondary structure the RNA is likely to have.
ModBase Predicted Comparative 3D Structure on Q96RQ3
The pictures above may be empty if there is no ModBase structure for the protein. The ModBase structure frequently covers just a fragment of the protein. You may be asked to log onto ModBase the first time you click on the pictures. It is simplest after logging in to just click on the picture again to get to the specific info on that model.
Orthologous Genes in Other Species
Orthologies between human, mouse, and rat are computed by taking the best BLASTP hit, and filtering out non-syntenic hits. For more distant species reciprocal-best BLASTP hits are used. Note that the absence of an ortholog in the table below may reflect incomplete annotations in the other species rather than a true absence of the orthologous gene.
